Application led August 16, 1911. Serial N o. 644,366.

T0 all whom it may concern Be it known that I, HENNING ADOLF OLssoN, a subject of the King of Sweden, and resident of Villa Sfvens 5, Gottenborg, in the Kingdom of Sweden, have in-l vented certain new andv useful Improvements in Ball-Retainers for Ball-Bearings Subjected to Axial Pressure, ofwhich the following is a specification, reference being had thereiIfto the accompanying drawing.

This invention relates to a retainer for the balls of ball-bearings subjected to axial pressure, which can be manufactured at a low price, can easily be used, owing to the fact that the balls can easily be mounted in the same, and besides is reliable and durable. 'llhe said retainer consists of a yielding ring of sheet metal, which is ll-shaped in cross section and the Shanks otwhich are parallel or substantially parallel to'theplane of the ring and are located at a distance from each other, which is shorter than the diameter of the ball. The said shanks are provided with circular recesses, the circumference of which is greater than a semicircle vbut does not form a complete circle, owing to the fact that the center point of the recessv is located at a distance from the edge of the shank which is shorter than the radius of the recess. Two recesses of this type, one proat proper distances from each other by the retainer 4. The said retainer consists of a stamped ring of sheet metal and lll-shaped in cross section. The two Shanks 5, 6 of the ring extending inward toward the center of the ring are parallel or substantially parallel to the plane of the ring, as 'shown in Fig. 2. ln each of the Shanks, at the edge of the same a recess 8 is provided for every ball of the series. The said recess is circular, so that the ball lits in the same, but has a shorter radius than the ball. The distance between the Shanks of the ring being besides shorter than the diameter ofthe ball, the ball is suliciently inclosed and nevertheless freeat both its sides, so that itcan rotate, bearing against the rings 2, 3. The yielding capacity of the Shanks would possibly be exceeded, as the ball is forced into the space between the same, if the recess 8 forms a complete circle. For that reason the recesses 8 are open inward toward the center of the retainer, the opening comprising, however, not more than one third of a circle or substantially so, consequently a shorter distance than a Semicircle. iOwing to this arrangement the ball can easily be forced into the recesses and then remains in the same with a sufficient play. In order to facilitate still more the said operation one 5 of the Shanks is somewhatwider than the other.

Having now described my invention, what I claim as newand desire'to secure by Letters Patent is:

1.. A ball retainer for ball bearings` subjected to axial-pressure, consisting of a yielding ring of sheet metal inverted U- shape in cross section, the said ring being provided with Shanks projecting'inwardly from itsv opposite edges substantially parallel with the plane of the ring, the said Shanks being located at a distance from each other less than the diameter-of the balls and provided with recesses for the balls, the said recesses being smaller than the balls and open at the edges of the Shanks to permit the balls to be snapped into the recesses in the Shanks by the yielding of the metal.

Q. A ball retainer for ball bearings subjected to axial pressure, consisting of a yielding ring of sheet metal inverted U- shape in cross section and provided with Shanks projecting inwardly from theopposite edges of the ring substantially parallel with the plane of the ring, the said Shanks being provided with recesses open in one of the Shanks at the edgeof the same, the size of the said recesses and the distance between the Shanks being so related to the balls that the latter will be retained in position after having been snapped in place by the yielding of the metal.

3. A ball retainer for ball bearings subjected to axial pressure, consistingol a yieldmg ring olf sheet metal inverted U-shape said shanks being provided with recessesfor the balls, the recesses being open at the edges of thel Shanks, the size of the recesses being less'than thesize of the balls and the Shanks being so spaced with reference to the size of 10 the balls that the latter will be retained in position when snapped in place by the yieldlng of the metal.

In Witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

HENNING ADOLF OLSSON.
